HiLo™ INTERCONNECT OVERVIEW BGA/LGA Socketing Module Interconnect Highs Lows Flexibility High Density: 0.8mm pitch and above Any Application: Production IC socket, • • • Low Profile: Socket height less than 2mm module-to-board connector, flex to PCB High Speed: 1 dB cut-off measured at 9.3 • Low Cost: A few cents per mated pair in • GHz Quick Delivery: Prototype quantities shipped • high volume production in 2 weeks High I/O: Available with over 2400 • • Low Tooling Cost: Tooling cost for custom positions Any Footprint: Not limited to standard arrays • footprints less than $1,000 or geometries. Design freedom for mixed pitch, • High Reliability: Proven dual-beam gold- selectively populated, and non-grid arrays plated high strength copper alloy contacts • Low Insertion Force: One ounce per • CTE Compliant: Designed to accommodate • High Speed Assembly: Pick and place contact thermal mismatch compatible Connectors: HiLo™ Interconnects

PRODUCT INFORMATION The HiLo system consists of two contacts: A pin (male) and socket (female) Dual beams make contact to pin J-Lead on bottom of contact is surface mount soldered to BGA pattern on PCB Socket (Female) Pin (Male) • Base material: Beryllium Copper • Base material: Phosphor Bronze (typical) • Plating: Selective Gold over Nickel (typical) • Plating: Gold over Nickel (typical) • Different contacts tooled for different pitch • Diameter 0.3mm (0.012”) for 1mm pitch + • Diameter 0.2mm (0.008”) for 0.8mm pitch + Connectors: HiLo™ Interconnects

PRODUCT INFORMATION HiLo™ connector housings are manufactured from drilled laminate instead of molded plastic: • Improved Solder Joint Reliability: For large area array connectors, a CTE mismatch between the connector and PCB materials can result in significant stresses and failures under thermal cycling applications. HiLo minimizes these CTE mismatch stresses by utilizing a laminate with a CTE similar to the customer’s PCB. • Better Flatness: Drilled laminate connectors also exhibit less warp and twist during reflow compared to molded connectors. ISI’s HiLo designs have a tendency to conform to the substrate material during reflow resulting in high quality, reliable solder joints. HiLo is available with the following laminate materials: Resin Tg X-Y CTE Dielectric Constant o C FR4 125 10-14 3.9-4.5 o C High Temp Epoxy 210 10-14 3.6-3.7 o C Polyimide 250 6-9 3.6 Connectors: HiLo™ Interconnects

HiLo™ MANUFACTURING HiLo uses a standard, high volume, production process to make custom product variants: • Data driven process: Engineering files load directly into production equipment • Standard panel size eliminates Precision routing High-accuracy, multi-head drilling job-specific tooling • Standard materials + standard process + unique data file = custom product • Automated optical inspection ensures quality on 100% of units manufactured Automated contact insertion Automated optical inspection Connectors: HiLo™ Interconnects

PRODUCT INFORMATION Typical Pin Field Socket Pin inserts into dual beam contact Configurations: This end of pin is soldered to PCB, BGA or LGA This end of pin is J-lead solders to inserted into socket PCB • Socket contacts are captured in three layers of laminate. • Pins are inserted into two layers of laminate and planarized. • Bottom layer holds contact barrel and serves as main structural body of socket. • Bottom layer is drilled at same diameter as pin to provide interference fit • Center layer is drilled at a larger diameter to allow contact beams to move • Top layer is drilled at larger diameter to provide clearance for solder joint • Thin top layer serves as a guide when inserting pin field Note: Drawings shown are for reference only. ISI manufactures with different materials, dimensions, etc. to suit various applications. Please consult ISI for accurate drawings for your application. Connectors: HiLo™ Interconnects
